SellerForge

SellerForge is an all-in-one, AI-powered growth platform built specifically for Amazon sellers, brand owners, and agencies. It connects securely to a seller's account through Amazon's official Selling Partner API (SP-API) and Amazon Advertising API, then layers AI on top of live account data to automate the work that normally requires a full PPC team, a copywriter, and an account manager. Amazon Advertising (PPC): SellerForge manages Sponsored Products and Sponsored Brands campaigns end to end — campaign, ad group, targeting, placement, and bid management with ACoS and TACoS tracking. Its AI Analysis surfaces wasted ad spend, flags campaigns above target ACoS, and recommends specific bid and keyword changes. A search-term workflow harvests winning keywords and negates zero-conversion terms (with automatic graduation negatives), while set-and-forget automations — Wasted Spend Killer, Keyword Harvester, Goal-Based Bid Optimizer, and Inventory-Aware Pause — keep accounts optimized between logins. Dayparting, negative targeting, diagnostics, and a full change log complete the module. Listing Optimization: An AI Listing Audit scores titles, bullets, descriptions, images, and backend keywords, and benchmarks each listing for Amazon's A10 algorithm, the COSMO semantic graph, and Alexa for Shopping (formerly Rufus) readiness, including image-compliance analysis. The AI Listing Builder generates and refines fully optimized, compliance-checked listings with category and price recommendations. Keyword Research & Rank Tracking: Reverse-ASIN keyword discovery, intent tagging, search-volume and Amazon Brand Analytics signals, and per-ASIN keyword rank tracking help sellers find and defend high-value search terms. Account Health & Defense: SellerForge detects FBA reimbursement opportunities and prepares cases, and generates Plans of Action (POAs), appeal letters, and escalation plans to resolve suspensions and policy issues. Operations, Insights & Reporting: Sales and inventory forecasting, customer and repeat-purchase insights, promotions planning, automated feedback requests, a weekly AI-written business report, and a Deliverable Builder that exports investor updates, board decks, and ad-performance reports as PowerPoint and PDF. A built-in AI assistant answers questions grounded in the seller's own data. Available in Core, Growth, and Pro plans across multiple Amazon marketplaces and currencies, SellerForge replaces a fragmented tool stack and an expensive agency with a single, AI-driven platform. Starting at $49/month. Learn more at https://www.sellerforge.ai.
